About PMET Resources Inc.
PMET Resources Inc. is a critical pegmatite mineral exploration and development company focused on advancing its 100% district-wide Shaakichiuwaanaan property located in the Eeyou Istchee Baie-James region of Quebec, Canada, which is accessible year-round by an all-weather road and close to regional hydroelectric infrastructure.
In late 2025, the Company announced a positive lithium-only feasibility study on the CV5 pegmatite (the “Feasibility Study”) and declared an initial mineral reserve of 84.3 Mt at 1.26% Li.2O (Probable)1. The study describes the potential for a competitive and globally significant high-grade lithium project targeting up to ~800 ktpa of spodumene concentrate using a simple dense media separation (“DMS”) process flowsheet only. Additionally, the results highlight Shaakichiuwaanan as a potential critical minerals powerhouse in North America with significant opportunities for tantalum and cesium in addition to lithium.
